A Comparison Study of Mechanism: Cu2+ Adsorption on Different Adsorbents and Their Surface-Modified Adsorbents

Figure 2

Four kinetic models for the adsorption of Cu2+ by OCB, CB, organic bentonite, and bentonite. The solid line is the fit to the four order models: (a) the first-order model, (b) the second-order model, (c) the pseudo first-order model, and (d) the pseudo second-order model.
